Keeps things super hot
Does great at keeping things HOT. I poured my tea from a boiling kettle, forgot about it for an hour and it was still too hot to drink. It's not leak proof and it doesn't fit great in my car cupholder but it's still good to take my tea or hot chocolate to work.

Excellent
My advice don't buy any other make. Lock n lock are the best. Tea stays hot for a couple of hours. Really good. Highly recommend

Tight and well protected cover
Dislike- somehow the hot water does not keep warm longer. Like - easy to sip and drink.
